Název v původním jazyce

A wide difference in susceptibility to nitrite between Eurasian perch (Perca fluviatilis L.) and largemouth bass (Micropterus salmoides Lac.)

Popis výsledku v původním jazyce

Influence of nitrite on two fish species, Eurasian perch (Perca fluviatilis L.) and largemouth bass (Micropterus salmoides Lac,pSde), was assessed in two acute toxicity tests. In the first one, lethal concentrations (48hLC50) of nitrite were estimated at11 mg l(-1) NO2 (-) for perch and 882 mg l(-1) NO2 (-) for bass. In the second test, fishes were exposed for 48 h to concentrations representing A1/4 and A1/2 value of 48hLC50 for each species. This test showed that the higher nitrite concentration in the water the higher methaemoglobin content in the blood, and nitrite levels in the blood plasma were observed in both species. On the other hand, leucocyte count showed opposite trend. Activity of NADH-methaemoglobin reductase was markedly lower in largemouth bass compared to Eurasian perch and was stimulated by nitrite exposure in neither of the species.
